IMPROVEMENT IN ROVlNG-FRAMES.

Specication forming part of Letters Patent No. 120,209, dated October24, 1871i.

To all 'whom t may concern:

Be it known that we, EUsTIs P. MORGAN, of Saco, in the county of Yorkand State of Maine, and JAMEs H. MCMULLAN, of Biddeford, in the countyand State aforesaid, have invented a new and useful Improvement inRoving-Frames; and we do hereby declare that the following is a full andexact description of the same, reference being had to the accompanyingdrawing making a part of this specication.

Ourpresent improvements relate mainly to varions parts of theroving-frame for which Letters Patent were issued to us on the 25th dayof May, 1869; but may also be used in connection with speeders,iiy-irames, slubbers, or other machines for making rovings in theprocess of the cotton manufacture or of other fibrous substances.

The main features of novelty embraced in this machine are two, viz.:Means for preventing the fracture or injury of the machine in case acertain part of the mechanism as heretofore usedi'ails to effect theproper changes at the right time and in the right manner 5 and alsomeans for causing the machine to be stopped either during the upwa-rd ordownward motion of the bobbin-rail, at any definite point, in order thatthe end77 of the roving on the outer layer may, when the bobbins aredofied, occupy any required position.

For the general principle and construction of the machine for makingroving we would refer to the Letters Patent before named 5 and we willnow describe in full the nature of our speciiic improvements, which arefully represented in the drawing making a part of this specication.

Sheet A, elevation from the back side of the machine, looking toward thespindles. Sheet B, elevation of the parts nearest to the driving end, asseen from the opposite end, with detached sketch of the lever L andspiral spring 1. Sheet G,elevation, looking toward the weights W W fromthe driving end, with plans of the tumbler T.

The bobbin -rail R is raised and lowered by means of the quadrants Q,which have their center of motion near the back of the frame, at 30.Friction-pulleys 20 are attached to the rail R, and rest upon the curveden ds ofthe quadrants, these parts being placed at such intervalsthroughout the length of the frame as to give sufficient support andsteadiness to the rail. The lower part Vof each quadrant is providedwith teeth 23, which engage with the gear 3l on the bottom shaft 10,which revolves in one direction to raise the rail R and the bobbin 13,and in the other direction to lower them. This alternate movement oftheshaft 10 in opposite direction is effected by the beveled gears U andC', which are driven success ively by the pinion 9 attached to the lowerend ofthe diagonal shaft 8, which is driven by gear 15 and the pinion Zafiixed to the top shaft H. This shaft is driven by the train of gears26 25 27 and the pulley P affixed to the same shaft 1l that carries thegear-wheel 27. The change of the pinion 9 from one of the wheels O tothe other, for the purpose of chan gin g the direction of the in otionof the rail It, is eii'ected by means ofthe eccentric E and its fork F,which is moved from right to left on the horizontal rod 21, and carrieswith it the stand 32 that holds the diagonal shaft 8 and its attachedpinion 9. The spiral spring 1 holds the lever L in contact with one ofthe pins 6 6 at the bottom of the eccentric; this spring, when allowedto act by the escape of' one ofthe dogs D or D from one ofthe plates 23, effecting the change of the pinion 9 by forcing the lever L, havingan incline on its end, against one of the pins 6 6', and thus causingthe shaft G to turn so far that the pinion N Y may engage one of thesections of teeth in the wheel M. rllhe time of making this change isgoverned by the vertical shaft G, and other parts acting in connectionwith it. The crown-wheel M, iiXed to the top of the shaft G, has twospaces on opposite' sides that are not provided with teeth. rllhe teethare thus divided into two sections, and when the driving-pinion N isover either of these spaces, which is the case when the rail 1t isrising or falling, no motion is communicated to the shaft G, and thereis no movement of the eccentric E and its attached parts 5 but when theteeth M engage with the pinion N the shaft G and the eccentric make half`a revolution and change the pinion 9 from C toO or from C to O. rlhisengagement of the crown-wheel M with the drivin g-pinion N occurs whenthe dogs D D', which are attached t0 the shaft G, escape over or underthe traversing-plates 2 or 3, which rise and fall with thel rail R,being connected with it by the bracket or brace 33. The escape of thedog D takes place when the rail has reached its lowest point, and of thedog D when it has reached its highest point. In ease the spring 1 failsto act upon the lever L, as above described, one of the plate-jaws J J'pushes one of the fingers I I' and turns the shaft G far enough aroundto cause the engagement of the pinion N a-nd wheel M, when the shaft Gand eccentric E will make half a revolution and reverse the motion ofthe bobbin-rail R, one of the lingers just touching one of the jaws whenthe dog is leaving the end of one of the traversing-plates. The actionof this mechanism prevents the breakage of the machine, which wouldoccur if the rail motion was not reversed. When a new set of bobbins isto be started the horizontal-toothed rack 34, near the top of the frame,is moved by hand upon the bar 35 until it is in contact with theadjustable stop 37. This motion turns the pinion 40 and the pulley 0,that carries a cord, 22, leading over a iiXed pulley, 5l, and lifts theweight WV'. This weight tends constantly to draw the rack 34 back, theforce being exerted at the pin 45 that fixed in the shaft 4l, and restsin a slot at the top of the clutch 47. The clutch, the pinion 40, andthe pulley 0 move with the hollow shaft 46 that turns on the verticalshaft 41, the latter shaft being supported by the stand 44. When thehollow shaft is turned backward by the motion of the rack 34 the clutch47 is disengaged. The shaft 4l also carries the horizontalescape-wheel43,havin g teeth or leaves placed alternately on itsopposite sides. These teeth are embraced by the forked lever 48, havingits center at 52. On the opposite side of this center there is anattached ilexible arm, 49, that carries at its end the stud 50. This armis stiff enough to impart motion to the fork 48, but is made slightlyflexible, in order to give easy action and prevent injury in case ofderangement of the parts. The stud 50, with its attached arm and fork,is raised and lowered by the scroll-cam K iixed to the shaft G, allowingat each half revolution a tooth to escape on 43 and impart a quick shortmotion to the rack 34. As the combined length of the plates 2 and 3, bythe action of the screws A and B, grows less and less the dogs D escapesooner and cause the rail R to reverse oftener, thus giving it a shortertraverse, and forming the conical or tapered ends of the full bobbin 53.If the last layer of the roving comes at the angle 54, where the taperedpart of the bobbin begins, the roving is liable to unwind and causewaste. lt is therefore desirable that the frame stop when the rail R isin such a position that the end of roving may be left ata short distancefrom the angle 54 or 54'. This is effected as described below. Theshipper-lever X has two arms. The end of the arm X' has a stud, 24, thatrests in a notch made in the shipper-trigger Y Y' the end X' extendsupward and rests against the stud S' on the shipper S. The center ofmotion of the shipper-lever is at 57, and the long arm X has anadjustable weight, 56. The shipper-trigger turns on the center 58, andhas an arm, Y, that extends downward to the level of the stop 36 that isscrewed to the rack 34. A suspended curved rod, U, having its center at59, has near its lower end a triangular friction-stud, 28, and at itsupper en d a notch, 60. The arm X of the tri-armed shipper-lever is justabove this notch, lbut does not quite touch it. At every motion of therail R the tumbler T, which is supported by a bracket, 6l, screwed tothe rail, comes in contact with the stud 28, and the notch in thesuspended arm U is thrown outward; but the shipper-arm X does-not fall,as it is held up bythe shippertrigger Y'. When the rack 34 reaches theend of its traverse and the bobbin is full the piece 36 moves the arm Yand releases the stud 24 from the notch in the arm Y', the weight 56then depresses the arm X and it falls, as the notch 60 in the suspendedarm U docs not come back to its place. NVhen this fall takes place thearm X acts on the stud S' and throws the shipper S outward, moving thebelt from the driving-pulleyl? to the loose pulley P'. The stud 28 isadjustable vertically, and can be placed at any required position withreference to the rail lt, so that the action of the tumbler T may takeplace at the right moment, and the end of the roving be left at a shortdistance from the angle 54 or 54' of the full bobbin. The tumbler Toccupies the position shown on main view and in the right-hand detachedview of Sheet C, when the frame is required to stop as the rail R isgoing up. If the frame is to stop when the rail is going down theposition of the tumbler is reversed, as shown on the left side of SheetG. An arm, 62, projects from the tumbler in such. a position that itsmotion may be checked by stops on the stand that supports the tumbler.

What we claim isl. The combination, with the eccentric E, the fork F,the shaft G, and the dogs D D', of the iingers l l', the plate-j aws JJ', or their equivalents, for the purpose of setting in operation themechanism for causing the reversal ofthe bobbin-rail lt in case of thebreakage or non-action of the spring l.

2. The combination of the shipper S, the shipper-lever X X' X", thetrigger Y Y', the vertical rod U, the tumbler T, a-nd the iiction-stud28, or their equivalents, for stopping the frame automatically when thelast coil on the outside of the bobbin of roving is near to the conicalor beveled end of the bobbin, substantially as herein described.
